Allow Creation of Asset Accounts That Don't Exist Yet and Add `Blocked` Status #13843

joepetrowski · 2023-04-06T12:43:03Z

Adds new dispatchables touch_other and refund_other, allowing an asset class's Freezer or Admin to create an account with zero balance in the asset class by placing a deposit; and to remove/refund. The existence of the account is represented by a new ExistenceReason::DepositFrom variant.
Adds a new trait AccountTouch that allows other pallets to touch an account into existence for an asset class.
Adds a new account status of Blocked (invoked by the asset class's Freezer via the new dispatchable block). Unlike Frozen, which prevents withdrawals from an account, Blocked prevents both withdrawals from and deposits into the blocked account. The account can be returned to its unrestricted (Liquid) state via the existing thaw function.

I am missing a test to check that an account does not get reaped in case reason matches ExistenceReason::DepositHeld(_) for refund() and refund_other()

Good call, if someone places a deposit, someone else shouldn't be able to remove that account. Updated logic / test.

Unblocking, as it turned out, the migration is not needed since the encoded value stays the same despite the AssetAccount.status field had got changed

What happens if a local asset's deposit is different to a foreign asset? Doesn't AccountTouch::deposit_required() need to take an AssetId to be able to answer that question?

gavofyork · 2023-05-15T13:47:55Z

Seems a reasonable point; @muharem ^^^?
